Buying the right barcode scanner for Royal Mail 2D Barcodes

Hi all,

I want to buy a barcode scanner that will scan the Royal Mail 2d barcodes that are printed by Royal Mail DMO, that will read the barcode straight into Packing Partner to mark an order as shipped with the barcode recorded.

Are there different types of 2D barcode? What should I look for to ensure the barcode scanner that I buy will read the Royal Mail 2D barcode?
